IndexingThe Indexing topology takes data ingested into Kafka from enriched topologies and sends the data to an indexing bolt configured to write to HDFS and either Elasticsearch or Solr.

pcapPacket capture (pcap) is a performant C++ probe that captures network packets and streams them into Kafka. A pcap Storm topology then streams them into HCP. The purpose of including pcap source with HCP is to provide a middle tier in which to negotiate retrieving packet capture data that flows into HCP. This packet data is of a form that libpcap-based tools can read.
